IMPROVEMENT IN GUSSET-CONNECTIO NS FOR STEAM-BOILERS.

Specification forming part of Letters Patent No. 1 58,037, datedDecember 22, 1874; appl cation filed October 29, 1874.

To all whom it may concern:

Be it known that I, JAMES T. CONNELLY, of Oonnellsville, in the countyof Fayette and State of Pennsylvania, have invented certain new anduseful Improvements in Locomotive Steam-Boilers; and I do hereby declarethe following to be a full, clear, and exact description thereof,reference being had to the accompanying drawing, and to the letters ofreference marked thereon.

My invention relates to what is known as the wagon-top locomotivesteam-boiler and it consists in the construction of the gusset orconnection of one single plate, as will be hereinafter more fully setforth.

In order to enable others skilled in the art to which myinventionappertains to make and use the same, Iwill now proceed to describe itsconstruction and operation referring to the annexed drawing, which formsa part of this specification, and which represents a longitudinalvertical sect-ion of a wagon-top locomotive steam-boiler embodying myinvention.

G represents the so-called wagon top of a locomotive steam-boiler, towhich the gusset or connection A is riveted, by a single or double rowof rivets, F F, as desired. The gusset or connection A is made of asingle plate, out in proper shape, and bent around and fastened by adouble row of rivets, G, the same being on top. The large end B of thegusset is fastened to the wagon-top throat, and the smaller end D isriveted to the front shell H by a single row of rivets, F.

By the construction of the gusset or conreduced just at the point wherethe greatest' strain and expansion are by the reduction in the number ofseams.

Gussets have heretofore been made of a number of plates, necessitating anumber of seams; and it is well known that nearly all accidents occur byseams giving way and leaking. This has been attempted to be remedied bycalking, but this is even more destructive that the rivet-holes. This isentirely obviated by the construction of the gusset of a single plateproperly out out, as described.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The gusset or connection A of a boiler, made of asingle piece, taperedfrom its top, and provided with offsets, whereby more than one seam isavoided, substantially as set forth.

JAMES T. CONNELLY.
